Previous Discussion
TYNDP 2011-2020
> Current report covers:
• Demand scenario coming from TSOs (best estimates)
>
• An Average Daily Demand
• A High Daily Demand (1-in-20 in most countries)
• Annual demand scenarios coming from Eurogas, IEA and Primes
• An Average Daily Demand
Only TSOs and Primes scenarios provide data on a country basis
SJWS #1 Input

forecasts
A list of criteria should be defined for consideration by TSOs when forecasting
demand, incl. a check list for national Renewables Action Plans (NREAPs)
Transparency of assumptions and the origin of the forecast may be more
important than a common set of criteria
It is necessary to combine bottom-up and top-down approach

Improvement directions
1.
Upgrade the consistency and transparency in the assumptions
and methodologies
2.
Attention to power generation dynamics: link between
electricity and gas systems

and the national ten-year network development plans.
The peak demand values, calculated under the national standards, - The Design
Case - define the network requirements in terms of transmission capacity
determining the network development needs.
Other peak demand values – Simultaneous and Unsimultaneous peak – will be
estimated under a common methodology, incorporating a top-down approach
into the Entsog’s bottom-up scenario.
5
Transparency: assumptions and methodologies
Entsog’s bottom-up demand scenario
Why the top-down approach is limited to the definition of peak cases
>
>
>
The methodologies followed by each TSO to produce demand forecasts are
very diverse – consequently the same diversity is found in the assumptions
required, not only on the values but also on the parameters defining the
scenario.
GPD and Population – being used in most of the countries – may be useful for
comparison purposes.
Other factors broadly considered in the scenario definition are the industrial
activity and the energy efficiency. The parameters measuring these factors
are very heterogeneous as they are adapted to the specific features of gas
consumers in each country (e.g. the definition of industrial sectors) making
difficult the comparison.
6
Transparency: assumptions and methodologies
Entsog’s bottom-up demand scenario
Why only one single scenario
>
Even when for many of the countries, the demand forecasting is done with
some sensitivity analysis over a reference scenario, the heterogeneity of the
parameters considered in the sensitivity prevent their addition: The bottomup scenario is restricted to the aggregation of the reference scenarios.
>
Generally, in the development of forecasts, TSOs are already taking into
account political decisions having an impact on gas demand. Therefore we
can not differentiate between gas demand scenarios with/without
consideration of EU political goals.

Consideration of EU political goals

Overall CO2 emissions reduction: -20% compared to 1990 levels
20% increase in energy efficiency equalling 368 Mtoe reduction of energy
consumption compared with projected levels in 2007.
20% of EU energy consumption to come from renewable resources
The global EU targets are translated into national targets in the National
Reform Programmes and National Renewables Action Plans

Consideration of EU political goals
The National Renewables Action Plans

Focused on the contribution of the renewables to the energy mix, and its
enhancement. The NREAPs are a feeble source of information with
regards to natural gas demand.
Again, the heterogeneity between plans makes difficult the comparison.

Roadmap 2050
>

The Communication “Energy Roadmap 2050”, commits the EU to reduce
greenhouse gas emissions to 80-95% below 1990 levels by 2050, being
the basis for developing a long-term European framework together with
all stakeholders.
The roadmap provides several – PRIMES – scenarios (EU27 aggregates):
CURRENT TREND SCENARIOS
1. Reference scenario with 4
sensitivities:
1.Low energy import prices
2.High energy import prices
3.High GDP
4.Low GDP
2. Current policies Initiatives ( Including
actions concerning “Energy
efficiency plan” an “Energy Taxation
Directive”
DECARBONISATION SCENARIOS
1. High Energy Efficiency
2. Diversified supply technologies
3. High renewable energy sources
(RES)
4. Delayed CCS
5. Low Nuclear
10
Consideration of EU political goals
Roadmap 2050

None of the decarbonisation scenarios is defined as a realistic “road” to
be followed. The aim of these 5 decarbonisation scenarios is the
delimitation of the envelope of energy consumption patterns that could
lead to the achievement of the decarbonisation target.
The horizon of the Roadmap 2050 goes far beyond the horizon of TYNDP
2023, while the main divergences between scenarios come after 2025.
From the PRIMES extensive description of scenarios, some parameters

Consideration of EU political goals
Roadmap 2050
Why the roadmap scenarios cannot be fed and analyzed in the network modeling
>
Lack of geographical disaggregation: demand figures are required at
country/balancing zone level
>
Yearly figures ~ Volumes: The more relevant demand figures defining the
network adequacy are the peak day.
>
The yearly figures cannot be directly translated into daily figures (- x %
yearly volume is not the same – x % of peak day demand). The demand
modulation is directly linked with the characteristics of the gas
consumers, therefore the assumptions considered in the different
scenarios implying changes in the gas demand breakdown will influence
the peak demands.

The increase of installed capacity and the reduction of the yearly power generation from
gas, lead to a clear increase in the intermittency of gas fired power stations, and
consequently on the flexibility required to the associated gas transmission facilities.

In every resilience test scenario, supply has been kept as close as possible to the
Reference Case while minimizing potential demand curtailment or investment gap
and staying within the supply potential range of each source
Supply mix in Reference Case is then used only to produce a reasonable
scenario but has no influence on gap identification

overestimation of the daily flexibility. Flexibility should remain constant rather than
increase with yearly values.
Nearly all pipe gas imported from outside Europe is delivered under long-term
contracts.
LNG treatment: some established LNG chains are dedicated to some terminals and
can be treated similar to pipeline gas, whereas most of the newer LNG projects
were developed for global market. Peak situations should be primarily be modeled
as a mix of underground gas storages and pipe gas supply
The behavior of LNG supply should reflect the dependency to price signal, high
prices often occurring under peak situation. Such situation may lead to ship
diversion or reloading and impact LNG tank management in order to provide high
flexible supply to the European market. Such features are clearly different than pipe
gas supply.
Maximum flexibility of Algerian, Libyan and Norwegian supplies is nearly reached
25
TYNDP 2011-2020 Feedback
General consideration on supply approach
> Consideration of supply limitation makes scenarios more realistic
> Ministerial sources could be too optimistic
> Non-conventional gas should be considered
> Dialogue with producers should be maintained and enhanced
> Consideration of ramp-up phases
> Focus should be on existing (contracted) supply and ones associated with committed
projects

>
supply shares for the Reference Case
Methodology to define Reference Case supply is appropriate
The arrival of a new supply source should reduce the shares of the existing ones
Supply contractual constraints should be factored in the scenarios
More supply scenarios should be investigated

Proposed changes/improvements
1- Extensive description of the gas supplies in the previous years
>
>
Introducing the concept of the review in the TYNDP.
Possible topics to be covered:
> Supply patterns: load factors by source and route. Historical maximums.
Analysis of the % of the different sources used as base load, and margins
for flexibility. Analysis of the variations after the introduction of a new
route or source. Imports vs. National Production. Supply portfolio by type
(LNG vs. Pipeline) and country.
> Diversification of supply: EU/zones/countries.
> LNG: analysis of the origins: Even if LNG is considered in the modelling as
a single gas source, a deeper description of the imports should be done,
and a indicator may be defined to measure its benefits increasing the
diversification of supply.
